Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs mo isture from the air. If the
water content in the b rake fluid is too high, cor­
rosion in the brake system may resu lt afte r ape ­
riod of t ime. The boiling poi nt of the brake flu id
will also decrease cons iderably and decrease
b raking perfo rman ce.
Therefore, the brake fluid must be changed
every
two year s.
Always use new brake fluid wh ic h con­
forms to Fede ral Motor Veh icle Standard "FMVSS
1 16 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that yo u have the
brake fl uid changed by yo ur autho rized
Audi
dealer .
Your dealer has t he corre ct tools, t he
right brake fluid and the know-how to do this for
you.

s ur e yo u are using the correct brake fluid .
The correct type of brake flu id is also ind i­
cated on the b rake fluid reservo ir .
- The brake fluid m ust be new . Heavy use of
the brakes can cause a vapo r lock if the
